Emotion theorists have long held that a fundamental characteristic of an emotion is how its constituent processes change and interact over time. Assessing these temporal dynamics of emotion in the brain is critical for understanding the neural representation of emotions as well as advancing theories of emotional processing. We review the neuroimaging research on three temporal dynamic features of emotion: time of onset, duration, and resurgence and show how assessing these temporal dynamics in the brain have led to improved understanding (...) of the structure and function of emotional processes such as revealing which appraisals come first, how emotional processing endures both explicitly and implicitly, and that the resurgence of emotional processing may consist of either single or multiple processes.

Emotions are traditionally considered to be brief states that last for seconds or a few minutes at most. However, due to pioneering theoretical work of Frijda and recent empirical studies, it has become clear that the duration of emotions is actually highly variable with durations ranging from a few seconds to several hours, or even longer. We review research on determinants of emotion duration. Three classes of determinants are identified: features related to the emotion-eliciting event, emotion itself, and emotion-experiencing person. (...) Initial evidence on the psychological and neural mechanisms that underlie their effects is discussed. (shrink)
